To all whom it may concern:

Be it known that I, SOLOMON l/VILE, a citizenof the UnitedStates, and resident of Rochester, in the countyv of Monroel and State Vof. NewYork, have `invented certain new 'and useful Improvements in Slicing- Machines, Yof which lthe following is a speciiication. l c

The present invention relates to slicing machinesfandl an object thereof is to provide an improved clamping means for'the material to be sliced. A further object of the invention isr to provide a guard 'for the knife which will permit the ready cleaning of such knife. Another object isj to V,provide a movable member for guarding the effective cuttincr portion kof the knife during nonuse. still furtherobject is to provide a stripping ldevice for the knife which may be utilized as a guard for the "effective cutting portion of the knife when the machine is not m use. Y

To these and other ends the invention consists ofcertain parts and combinations of parts, all of which will be hereinafter' de. scribed, the novel features being pointed out in the appended claims.

Ref-errino more particularly to the drawings, 1ind1cates the main frame which has preferablya hook portion 2 at one side adapted to engage over the edge of a supportfjto hold th machin@ t0 Suchk `Support,v

a thumb screw .4 being'mounted in the hook portion to clampjthe frame to .the support 3. The yframe 1 has a shaft 5 journaled thereon and carrying a cutter atf'oneyend,` said cutter rpreferably being in the formof a speculate@ fteaeisraant. Patented 0615,13, 1921i;

diskfwith ,a peripheralv cutting edge. `The shaft also has .at its opposite 4end a crank handle 7 by which the shaft ,and the lcutter are turned.` t Y. l

Mounted tomove on the frame 1,. transversely of theshaft 5 is acarriage 8,:said 'carriage having guiding rods 9 thereon guided at 10 in the frame 1. l The carriage also has a rack 11 on its underside which mesheswith a pinion 12 on the shaft 5 so that as thev shaft 5 is turned, the carriage will be moved, the movement taking place in one direction as the shaft isturned in one direction, and in the other direction with the reversal of the rotation of the shaft. Thecarriage 8 also has L uides 13 on the upper face thereof and these Aguides are engaged by a table or carriage 14 which moves toward and from the plane Vof operation of the cutter 6. Movement of the carriage 14 on the carriage 8 may be effected through a lever 15 which is pivoted at 16tothe under side of the carriage 8 and haspivotedV thereto at 17 a tooth lever '18, the teeth of which l are adapted to cooperate with a 4tooth 19 secured to the under side ofthec'arriage 14. A spring 2O connects the lever18 with the lever 15 and a spring 21 connects the lever 15 vwith the carriageS. The `lever 15 cooperates with a fixed abutment onthe main frame 1 as the carriage reaches lthe end of its movement just prior to the cutting 'action, thus causing the lever 18 'to be shifted and through its engagement with the tooth 19, to shift the'carriage 14 on the carriage 8. The amount of this movement may be determined by an adjustable stop 22 which is mounted on the carriage '8 and cooperates with an end 23 on the lever 15. Movement of the lever 18 out of cooperation with 'the tooth 19 to permit the carriage `14 to be moved away from the plane `of the 'cutter may be effectedby the end 24 jof the lever 18. No claim is made perse in this application to the hereinbofore described parts.

One of the features of this invention is the means forclamping the material to the carriage 14. This means comprises al noncircular post 25fprojected upwardly from the carriage 14 near that edge thereof adi thumb nut Qb operates.

jacent the cutter V6 and havingan upper screw threaded portion 25a on which a ates a clamping bar 26 which has a sleeve V2'? atone end fitting/loosely onV the-post, the of through the sleevebeing of .sub-H' stantially the same cross sectionas thatof VthepostL The under side of th'eclamping baris provided with aknife edge '28 extendopenin ing longitudinally'of said bar, this vedge being substantially'olf-er the edge of the carv riage `14 l"which isfnearest the cutter; ln

Y the guard for the Aknife edge which .com-V prises a ring segment 29 preferably. hinged order to "hold thematerial,A the latter is placed upon the carriage 14 and the clampingbar is moved downwardly on the post `25 tocompress the material. V'lhethuinb nut 25h isthen turned to khold the bar in' its adjustedposition. The knife edge with 'the adjacent edge of the table 14 thus holds the material-against movementon the carriage 14 Vduring the cutting action.

Still another feature of this invention is .the latter in its upright or guarding position.v

The segmental ring guard exposes that portion of the knife which operates Von the material being cut, onev end of the segment being below the plane ofmovement of the table or carriage 14 and the otherA en being above such plane.

With the end in lview ofV providing a' guard for the exposed portion of the knife when the latter is not in use and for stripping the material from the knife as the latter 'cuts the material, there is provided a member 33 which is pivoted at 34 to that end of the ring segment belowpthe plane of movement of the table or carriage. 14, its upper end being adapt-ed to be connected with the end of the segment above the carriage 14. To Vpermit this connection it is preferred to provide the member 33 on its kinner face with two lugs 35 spaced apart a distance suflicient to receive vthe upper end of the guard 29 between them as shown in Figs. 9 to 11, there being sufficient resiliency in the member v33 and link 29 to'permit the parts to be snapped into and out of interlocking relation. This member 33 also serves to strip the material from the rotary knife 6 and to this end it is provided with a rib or portion 86 which will bear closely against the outer face ofthe knife when the member 33 is in'lowered position as indicated in dotted lines in Fig. 2. rThis lowered position may be maintained by providing an On this post operfor the knife.A

abutment 37 on the member. 33 for coperating with an abutment 38 on the ring 29.

The detai'lrconstruction of the machine is immaterial so Y.far as this invent-ion is concerneldf vIn this instance, when the shaft 5 is turned in one direction, the carriage A8 shifts in one direction and theV- reversal of lthe movement of the` shaft reverses the movement of the carriage 8. J ust before the carriage 8 startson its movement to carry the material towardthe'knife", the carriage A14'V is automatically shifted 'a ,desired distance toward the .plane ofthe' knifefin` order to carry th'e'jmaterial intothe path of the knifej i The material isheld firmly by thecla'mp on the carriage 14. [The guard i's`pivoted to l permit the cleaningof the knife' and a' movable member isl provided for. the, effective cutting portion, V'said member being movable to a position where it willact as a stripper Vhat I claim as'my invention and, desire to secureby Letters Patent is: i

a cutter movable on the frame, acarriage for supporting the material to be sliced mov-l able transversely of the plane of operation of the cutter, :and a clamping bar mounted on said carriage and -havinga knife edge for cooperating with the -materialonthe carriage, said knife edge being situatedsub-V stantially over the forward edge of ythevcarriage so that the ed e of the carriage cooperates with the kni e edge to hold. the mav 'member movable to expose and to cover the portion of the lcutter which isexposed by the guard.
